The Lowdown
Alright, it’s Rusty here. Look, I’ve been staring at Kennebunk Beach for the next 16 days, and I’ll be straight with you—it’s a tough stretch. There’s no surf to get excited about for the whole run. The first real swell that shows any teeth doesn't arrive until Thursday the 3rd of September, but even then, it’s a messy 6ft from the SSE with a short period of just 6 seconds. That’s a weak, bumpy, close-out machine (combined energy 206), and with onshore wind, it’s more of a washing machine than a wave you’d want to paddle for. After that, we’re looking at a long, bleak gap. From the 4th right through to the 14th of September, the swell stays tiny, mostly between 0.7ft and 3ft, with low energy readings (mostly between 9 and 84). The wind is a mix of cross-onshore and onshore, which just adds chop to nothing. There’s a glimpse of cleaner conditions on the 5th and 6th with offshore and cross-off winds, but the swell is barely there. The morning of the 6th has clean 2ft from the ENE with a light offshore, which would be a fun little session on a longboard if you were desperate, but it’s not worth a drive. The glassy conditions on the morning of the 13th of September are a tease—1ft, clean, calm, but flat. The only slightly more energetic moment comes on the afternoon of the 14th of September, with a bump to 5ft from the S (combined energy 103), but it’s a short-period windswell (5 seconds) and the cross-onshore wind ruins it. After that, the 15th offers a weird little long-period spike (15 seconds from the E) but with a height of just 0.3ft—a ghost swell. Kennebunk Beach is a sheltered spot, and this forecast shows why: it needs a proper angle to work, and it just doesn’t get it. For the entire 16-day window, there are no days I’d recommend paddling out. It’s a blank run, and for this area, that’s not unusual when the swell direction is wrong. Hang tight, check the charts next week.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
